| Abstract: |
We present the results of an analysis of 21 planetary nebulae towards
the Galactic Bulge investigating the mixed-chemistry phenomenon. We
show a correlation between the morphology of the nebulae using HST
images and the presence of PAHs in oxygen-rich environments. The PAHs
could either arise from ISM sweep-up, or from internal processing.
The relation to morphology favors the latter. |
